Where to Apply Brake Grease on Brembos

[noahg]

I know this might sound like a dumb question but where am I supposed to put the brake pad lubricant on the front pads? I've only ever changed brakes on single-piston basic calipers and I've always put it on the back of the pad and on the ears of the pad where they contact the caliper but given that these brembos are different I would like to know where I need to lube them up. I've watched a few youtube videos but haven't heard a single person mention brake lube. Any suggestions?

No lube necessary. Do make sure you clean the pins really good, to allow easy reinstallation and so the pads can slide on them. If there are any gouges or wear on the pins (enough for your fingernail to catch), get new ones.

Lubricate the back of the pads and the ears and the pins.

ears?

you mean these? these are from the NON-BREMBO brakes
this thread is regarding the BREMBO brakes




Brembo brakes have no "ears"
Just flat rectangular backing plates (the only ears are the weights which do not contact anything)

the word "grease" does exist on this page --> https://www.kstinger.com/front_disc_brake-609.html
but it is only in the non BREMBO brake section, or perhaps it can be read as - applies to all

2.	Check that grease is applied to sliding contact points and check the pad and backing metal for damage.

I lightly grease the sides and I spray the back with the red sticky spray, forgot what it's called. no noise issues here.

that's it. I have a can of the CRC one.

I put a very light coat on the pad backing, like a wipe with my finger and a touch on the pad contact area of the caliper. A very thin coat.

Ears are the part of the pad the pins slide through where the weights are, I'd lube the pin and the inside of those ears since they will be sliding. Is it necessary for them to operate? No, will it possible keep thing quiet, yes. I also lightly lubed the slides of the pads where they contacted the calipers. As far as Im concerned anything thats sliding metal on metal lubricating it can only help.

If the surfaces are exposed, grease won't stay long enough to help much. In fact, too much of it will just end up attracting dust, form grime, and wear out the very surface(s) you're trying to protect. You're much better off cleaning them thoroughly before reassembly.

You can grease the pins, if you're so inclined. Rub a very small amount all along the shaft of the pin, then wipe all of it off. What that does is pack the microscopic pores of the metal with tiny pockets of grease. The pins will feel slicker to the touch, even with clean fingers, but nothing enough for dust to adhere to. This basically helps reassembly and the initial movement with brand new pads, when repeated braking action will sort out alignment of all the parts relative to each other. After a while heat produced from normal braking will evaporate any remaing surface film of grease from all the exposed parts. By then, the pads should have already settled into position and will move very little after that.

Compound on the back of the pads are unnecessary. If the goal is to quiet the brakes and dampen vibration, there are typically already anti-rattle clips and mass dampeners (those goofy looking ears) to reduced both low and high frequency vibration that cause brake VNH. Yeah, auto parts store will be all too glad to sell you stuff that supposedly help. Hey... $1.29 that does absolutely nothing is a great upsell and profit margin adder.
